A new refrigerant gas with a Direct Global Warming Potential (DGWP)
below the 150 limit set by the European Union is undergoing tests. A
company called Ineos Fluor developed the refrigerant gas, which promises
many of the advantages of current fluorinated refrigerant gases and may
offer an alternative to R134a in vehicle air-conditioning systems,
including motorhomes. The phase out of R134a in Europe is set for 2011.
Ineos claims the refrigerant is compatible with current
automotive air-conditioning systems, has no ozone depletion potential
and a very low DGWP. It is also is supposed to provide similar
performance to R134a when used in existing systems.
